The rocket attack, the second since the cease-fire took effect, led to a call for retaliation by Israel’s Foreign Minister while Palestinians charged that the continued closure of crossings violated terms of the cease-fire.

Despite the breach, Israel dispatched an envoy to Egypt in hopes of negotiating a prisoner swap with Gaza’s ruling Islamic Hamas.

The Al Aqsa Martyrs Brigades, a violent offshoot of Palestinian President Mahmoud Abbas’ Fatah, claimed responsibility for firing the rockets Thursday. One exploded harmlessly in a field, the military said, refusing to disclose where the other landed. A statement from the militant group demanded that Israel halt its military operations in the West Bank.

The truce, hammered out by Egypt over months of separate talks with Israel and Hamas, does not include the West Bank. On Tuesday, Islamic Jihad fired three rockets at Israel, wounding two people, linking the attack to an Israeli raid in the West Bank.

Foreign Minister Tzipi Livni said it should not matter who was behind the rocket attack.

“I am not interested in who fired and who didn’t fire at Israel,” she told reporters. “It is a violation, and Israel needs to respond immediately, militarily, for every violation.”

Previous truces have come apart quickly because Gaza militants claimed the right to retaliate for Israeli raids in the West Bank.

Of course the truces come apart. As muhammad the pedophile did in the old times, the truce is merely meant to buy the jihadists time to re-arm so they can strike again. They are just following the teachings of the quran.
